- Rewrite each of the following as an expression of x which does not involve any logs<span>.? Can someone show me ... Best Answer: To do it you have to know that 1000 = 10³ ; </span>100<span> = 10² ; .01 = 10^-2 </span>log 10<span>^3x = 3x 10^(2logx) = x²</span>
Answer:
x = ± 10
Step-by-step explanation:
Given
x² - 100 = 0 ( add 100 to both sides )
x² = 100 ( take the square root of both sides )
x = ±
← note plus or minus, hence
x = ± 10
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
=
+ 
=
+ 
576 =
+ 169
= 576 - 169
= 407
x = 
= 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.
Answer:
264
Step-by-step explanation:
220-22=198
198/3=66 (which is 1/4)
